Potassium Metabisulfite 2oz

Potassium Metabisulfite, commonly abbreviated KMS, is a powdery, white, strongly sulfurous-smelling (burned match) chemical used in many food and beverage industries, as well as in breweries as an antioxidant.
When dissolved in water or beer, KMS releases free sulfite ions, and these are responsible for the antioxidative properties of the compound. KMS is by far the most popular antioxidant used in the brewing industry. KMS is also active in limiting growth of wild yeasts and bacteria in beer.

Free sulfite reacts very readily with and thus eliminates free oxygen in beer, but also with many intermediary chemicals compounds (most important, aldehydes and ketones) that can combine with free oxygen and gives a stale and papery-tasting to your beer.
